Exodus 29:31 YLT

²⁹  'And the holy garments which are Aaron's, are for his sons after him, to be anointed in them, and to consecrate in them their hand;

³⁰  seven days doth the priest in his stead (of his sons) put them on, when he goeth in unto the tent of meeting, to minister in the sanctuary.

³¹  'And the ram of the consecration thou dost take, and hast boiled its flesh in the holy place;

³²  and Aaron hath eaten -- his sons also -- the flesh of the ram, and the bread which 'is' in the basket, at the opening of the tent of meeting;

³³  and they have eaten those things by which there is atonement to consecrate their hand, to sanctify them; and a stranger doth not eat -- for they 'are' holy;
